Using the SCBs in a straight forward manner would only allow the driver to handle as many concurrent transactions as there are physical SCBs. To fully Adaptec 2940uw pro the SCSI bus and the devices on it, requires much more concurrency.

The solution to this problem is SCB Paging, a concept similar to memory paging. SCB paging takes advantage of the fact that devices usually disconnect from the SCSI bus Adaptec 2940uw pro long periods of time without talking to the controller.

The SCBs for disconnected transactions are only of use to the controller when the transfer is resumed. When the host queues another transaction for the controller to execute, Adaptec 2940uw pro controller firmware will use a free SCB if one is available.

This allows the controller to queue up to transactions regardless of the amount of SCB space. Since the local SCB space serves as a cache for disconnected transactions, the more SCB space available, the less host bus traffic consumed saving and restoring SCB data. Controllers with this problem have a 42 MHz clock crystal on them and run slightly above 10MHz.

This confuses the drive and hangs the bus. Although the Ultra2 and Ultra products have sufficient instruction ram space to support both the initiator Adaptec 2940uw pro target roles concurrently, this configuration is disabled in favor of allowing the target role to respond on multiple target ids.
